TL;DR: An experimental demonstration of power gain in quantum-dot cellular automata (QCA) devices, where charge configurations in quantum dots are used to encode and process binary information.
Abstract: We present an experimental demonstration of power gain in quantum-dot cellular automata (QCA) devices. Power gain is necessary in all practical electronic circuits where power dissipation leads to decay of logic levels. In QCA devices, charge configurations in quantum dots are used to encode and process binary information. The energy required to restore logic levels in QCA devices is drawn from the clock signal. We measure the energy flow through a clocked QCA latch and show that power gain is achieved.

TL;DR: Using arrays of micron-sized metal dots, operation of a QCA latch-inverter and a two-stage shift register is experimentally demonstrated.
Abstract: Quantum-Dot Cellular Automata (QCA) is a computational scheme utilizing the position of interacting single electrons within arrays of quantum dots ("cells") to encode and process binary information. Clocked QCA architectures can provide power gain, logic level restoration, and memory features. Using arrays of micron-sized metal dots, we experimentally demonstrate operation of a QCA latch-inverter and a two-stage shift register.

TL;DR: The experimental demonstration of a two-stage QCA shift register and an analysis of errors encountered in its operation are presented.
Abstract: Quantum-dot Cellular Automata (QCA) is a device architecture that uses the position of electrons in quantum-dot arrays to implement digital logic. We present the experimental demonstration of a two-stage QCA shift register and an analysis of errors encountered in its operation.

TL;DR: An experimental demonstration of novel Quantum-dot Cellular Automata devices based on clocked architecture -- a QCA latch and a two-bit QCA shift register.
Abstract: We present an experimental demonstration of novel Quantum-dot Cellular Automata (QCA) devices based on clocked architecture -- a QCA latch and a two-bit QCA shift register. The operation of the devices is demonstrated, and sources of the digital errors occurring in clocked QCA devices are discussed.© (2002) COPYRIGHT SPIE--The International Society for Optical Engineering.
